# Why Equated

> One record of your business. Every invoice, bill, payment, and entry in one place.

Your finances live in five places. Equated puts them in one.

## One record, everything in it

Every invoice, bill, receipt, and bank line is linked in the same ledger. Pay the invoice and accounts receivable closes. Link the receipt and the expense is backed. No reconstruction at month-end. You just look.

## Every action leaves a permanent mark

Your books are evidence. Every change (by you or your AI) is written permanently. What changed, who made it, which records were touched. The history is always there. Nothing can be silently edited.

<div className="diagram-wrap">
  <div className="diagram-surface" style={{ overflow:'hidden', padding:'0' }}>
    <div className="diagram-row">
      <span className="diagram-text">Confirmed invoice #1042</span>
      <span className="diagram-muted">2:41 PM · by you</span>
    </div>

    <div className="diagram-row">

    <div className="diagram-row">
      <span className="diagram-text">Confirmed transaction</span>
      <span className="diagram-muted">Yesterday · by you</span>
    </div>

    <div className="diagram-row" style={{ color:'#d1d5db' }}>
      <div>· · ·</div>
      <div className="diagram-muted" style={{ color:'#d1d5db' }}>more entries</div>
    </div>
  </div>

## AI that stays in bounds

Your AI can link receipts, confirm transactions, close accounts receivable, prepare reconciliations. It can only act through defined actions: attach evidence, post transaction, apply payment, create journal entry. No free-form edits. Every action is previewed before it runs. Every executed action is in the ledger forever.
